Datasets. We evaluate our approach on PASCAL VOC 2012, PASCAL-Context and MS-COCO datasets. The original PASCAL VOC 2012 dataset consists of 1464 training, 1449 validation, and 1456 test images covering 21 classes (one background class). An auxiliary dataset of 9118 training images is provided by [1]}. PASCAL-Context dataset is a whole scene parsing dataset containing 4998 training and 5105 testing images with dense semantic labels, and this dataset involves 60 classes (one background class). MS-COCO dataset contains 81 classes (one background class), 80k and 40k images for training and validation.
